18 Claims.

has been made to pass a slug or other unacceptl5 able coin through the device.

Another object of the invention is to provide a reliable and efficient coin-controlled mechanism of the coin-advancing slide typehaving revolving coin-scanning means associated therewith for governing and predetermining the proper movement or obstruction of the coinslide and thence the operation or non-operation of the apparatus towhich the coin slide structure is applied.

A further object is to provide a coin-controlled device embodying leveling means for testing con tact with the surface contour of a coin or slug to. govern and control the operative or non-operative movement of the coin-advancing slide as determined by the' structural characteristics of the coins or slugs inserted in the slide.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

Similar characters of reference indicate corresponding parts throughout the several views.

In its general organization my improved coln-. controlled mechanism comprises a body or guide. member in which a coin-receiving or advancing slide is mounted for properly delivering acceptable coins to a point of discharge and thereupon initiate the action of the vending machine, phonograph or like apparatus to which the mechanism is connected; a revolvable scanning device or means associated with the coin slide and designed to test or examine the coin or slug inserted in the slide for acceptance or rejection, such means acting to govern and control the operative or non-operative movement of the coin-advancing slide as determinedby the structural char acteristics of the coin or slug attempted to be passed through the device, whereby upon the result of the scanning test the coin slide is permitted its full operative stroke should an acceptable coin be inserted. in the coin slide, or, conversely, the coin slide is latched to prevent its full operative stroke should an unacceptable coin or slug be attempted to be passed through the device.

Referring now to the drawings, wherein a preferred embodiment of my invention is illustrated, it indicates a channeled body, frame or guide member having a discharge opening it at its rear end for the discharge of an acceptable coin, while forwardly of this opening the bottom side of the guide member has an opening I? which is substantially cross-shaped in plan and includes a, main rectangular-shaped portion and lateral portions I8 extending outwardly from the longitudinal side edges of the main portion ofsuch opening. Adjacent its front or outer end the guide member has an attaching plate [9 for securing it to the coin-controlled apparatus. Slidably mounted on this guide member is the coincoin is inserted in'the coin slide.

to a coin-discharging position.

receiving or advancing slide 20 having an aperture 2i therein for the reception of a coin, the coin being supported on the floor or bottom of the guide member during the movement of the slide. Also guided in the body member in that portion thereof rearwardly of the attaching plate l9 and disposed immediately over the adjoining rear portion of the coin silde 2a is a secondary slide or carrier 22 for the scanning device, which, during the initial stroke of the coin slide, is held against movement relative thereto and which during the remaining stroke of the coin slide is adapted to be coupled thereto to move simultaneously therewith for a purpose which will hereinafter appear. Adjacent its front end this secondary slide is provided with a circular opening 23 of smaller diameter than the coin slide aperture 2i, and rearwardly of this opening such secondary slide has a longitudinal slot 2 i into which extends a stop element or screw stud 25 borne by the coin slide, this stud abutting against the front end of such slot in the fully retracted position of the coin slide shown in Figure 4. A similar stop element 25* abuts against the rear end of such slot in the initial advanced position of the coin slide, so that upon the final stroke of the coin slide the secondary slide will move simultaneously therewith. It might be stated here that after a coin is inserted in the coin slide and the same advanced to the aforesaid initial position in which the stop 25" abuts the front end of the secondary slide notch 24, the coin is positioned axially of the circular opening 23 of the secondary slide, at which time the coin is forced upwardly by means hereinafter described, into surface contact with a roughened or radially-serrated coin-receiving recess 23 formed, in the bottom side of the secondary slide 22 about its opening 23, whereby the coin is bridged between the latter and the coin slide to move jointly therewith and at the same time be held against turning. In this position, the coin is set for a scanning test or examination to determine by the nature of the coin whether it is acceptable or not.

If acceptable, the coin slide may then be advanced its final stroke to discharge the coin through the opening I 6' of the guide member, and if not acceptable, the scanning means operates to prevent any appreciable further advance of the coin slide and acts to effectually latch the coin slide against any movement to advance it The scanning means, which is associated with the coin slide and by test or surface examination of the coins predetermines and governs the proper movement or obstructionof the coin slide depending on whether an acceptable coin or nonacceptable coin or slug is inserted in the coin slide, respectively, is indicated generally by the numeral 26 and is superposed over the coin slide for relatively revolvable and simultaneous longitudinal movement therewith when an acceptable When coins are not accepted under test by the scanning means, the scanning device is held or clutched against turning and operates to automatically effect a latching of the coin slide and prevent its full operative stroke to thereby thwart attempts of unscrupulous persons to operate the apparatus to which the coin mechanism is appliedby using spurious coins and slugs. In its preferred construction shown in the drawings,

this scanning means is constructed as follows: 'The, numeral 27 indicates a revolvable drum or cylinder provided at its upper end with a bottom side.

, and gear constitute in effect a unitary structure.

Extending through the cover 28 axially of the drum is a journal pin SQ which constitutes an upper bearingfor the drum and its upper end is provided with a slotted-head 35 in which is seated a tongue 35 of a bracket 3i whose upper end overhangs the drum in the manner shown in Figures 4, 5 and 6, and whose lower end or baseflange 33 is attached to the top side of the secondary slide 22 by screws 39 or like fasteners. A washer ill applied to the journal pin M and interposed between the top side of the cover and the pin-head serves to support this journal pin in its proper relative position to the drum. By this construction the bracket and journal pin provide a firm support for the upper end of the drum 2? and the tongue connection 36 between the bracket and the journal pin holds the latter against rotation, this pin being provided immediately below the cover with a clutching disk ii fixed thereto and having a plurality of radially-spaced teeth or stop elements 422 on its As will hereinafter appear, the coin-scanning mechanism carried by and housed within the drum Ell includes a part which is adapted to cooperate with one or another of these teeth to prevent rotation of the drum and its associated parts and in turn obstruct a full stroke movement to the coin slide 253.

Disposed at one side of the channel body 25 rearwardly of its attaching plate i8 is a shift-- able tappet bar 53 preferably of angle shape in cross section, the top flange thereof overhanging the top side of the-secondary slide and having a longitudinal row of teeth i t t'iereon forming a gear rack with which the gear SE of the drum 2? is adapted to engage to either roll thereover or be clutched therewith. The gear rack is of a length. to permit an operative turning movement of the drum and a longitudinal movement of the coin slide from the initial point of the scanning examination or test station. shown in Figure 5 to the point of coin discharge shown in Figure 6. The depending flange of thisrack bar is provided adjacent its opposite ends with longitudinal slots it with which screws l-6 borne by the slide bod engage for limiting the fore and aft movement of the rack bar relative to the slide body. A coil spring arranged in a pocket it formed in the contiguous faces of the rack bar and slide body and abutting at-its opposite ends against opposing lugs formed on the parts, respectively, serves to constantly urge the rack bar to a retracted normal rearward position with the front end. of its slots d5 abutting the stop screws it. The rear end of therack 'bar 43, at a predetermined time and under certain conditions in the movement of the coin slide and associated parts, is adapted to engage a normally-released trip dog til pivoted adjacent the front end of the slide body l5 in the path of travel of the rack bar for shifting such dog into latching engagement with one or another of Qa series, of teeth 5i formed in the adjoining lon- I 2,212,714 gi tudinal edge of the coin-advancing slide '20 to thereby arrest the coin slide and prevent its full operative stroke when the rack bar effects the tripping of the dog. A spring 52 applied to the dog normally'holds it clear of the adjoining teeth 51 in the coin slide. i y

Housed within the drum 2! is a leverage mechanism for controlling the movements of a locking pin or clutching element 53 into and out of coupling engagement with the toothed disk ll,

from one side of a plate 59 supported within the I upper portion of the drum below the toothed disk 4| and having a key or like the drum to turn therewith. The lever 5b which is disposed centrally of the drum between the companion levers 5t and 56 is pivoted at iii to the opposite side of the plate 59 on a depending The locking pin or clutching element 53 is mounted on the free end of the lever 55- and is guided in its vertical movements'in an opening 63 formed in the lever-supporting plate 59. A spring 64 is arranged in bearing contact with the lever 54 and tends constantly to swing it downwardly to. a position where its locking pin 53 isout of clutching range with the depending teeth of the disk M. such lever 5-4- is connected by a pin" 65; and slot 68 with the adjoining free end of the intermediatejlever 55. The lever St has a lateral Offset or arm til at its free end which normally connection SQ with overhangs and contacts with the short arm til 54 through the contacting arms El, 68 and the pin and slot connection 65, 65 to hold the lever 54 upwardly with its locking pin 53 projected intofl'the path of the teeth d2 of the disk 4!.

'By the pivotal and bearing contacts of the re,-

spective levers 5t, 55 and 56, the degree of movement' resulting'from the scanning tests and imparted to the respective levers, say, from the lever 56 to the pin-carrying lever 5a or from the intermediate lever 55 to such pin-carrying lever, is effectually multiplied so that a very small degree of movement imparted to. the aforesaid levers transmits a relativelylong degree of movementto the locking pin 53 in retracting it from or projecting it into clutching engagement with the toothed disk M.

3 at as to or from the toothed disk to clutch the scanning drum against turning or permit its turning to effect a complete operative stroke of the coin-slide, the surface contour or characteristic of any particular coin whether acceptable or unacceptable predetermining the movement imparted to theclutching pin. One of the means employed for this purpose consists of a leveling I unit for scanning the surface-contour of the coin and comprises a plurality of headed upright pins whose shanks engage corresponding openings ll formed in the bottom or hub of the drum 2? and whose heads are arranged in a well ,or recess it provided by an annular flange l3 rising from the top face of the bottom wall of the drum. "By preference, three or-these pins are employed and are spaced equidistant from one another about the turning axis of the drum, with their heads normally supporting the pins 'in their lowered position, such pins normally seeking such position by gravity where they are in position to be acted upon at their lower ends for upward displacement by the coin. Disposed over and in registering relation with the heads of these pins is a three-armed leveling plate or spider "it whose ends terminate in tongues 75 seated in upwardly-facing guide notches. it formed in the annular flange lit, wherebythis spider is held in proper relation to the respective leveling pins, the heads of the latter contacting the bottom side of the spider in the normal seated or lowered position of the latter so that any lift transmitted to the respective pins due to the uneven surface contour of the coin is immediately transmitted to the spider to accordingly change itselevation. Any appreciable movement transmitted to the spider-as for example, if thesurf-acecontour of a coin be such as to lift all three pins and accordingly elevate the spider uniform 1y vertically or substantially sois in turn transmitted to the leverage mechanism a l, 55 and and to this end the centrally-disposed lever 55 has a'depending lug ill thereon which normally contacts the center of the leveling spider l t.

Any change in elevation transmitted to the spider imparts an upward movement to the lever and ajcorr'esp'onding movement to the adjoining connected lever 5t to project the locking pin, should the displacement be sufficient to do so, into clutching engagement with the toothed disk i i. should. the surface character of the coin be such as to effect an elevation of but one or two of the levelingpins Hi, the degree of angular displacement transmitted to the spider or leveling plate M is very slight at the center thereof and is not sufficient to project the locking pin into its clutching position, indicating that the coin is of an acceptable type, insofar as its surface-test is con- Primarily these leveling pins operate on other than genuine or acceptable coins to effect a sufficient elevational displacement of the spider to project the locking pin 53 into clutching engagement with the toothed disk ll to hold the scanning drum 2? against turning, thereby preventing the full operative stroke being transmitted to the opening l t therein is an axially-disposed center pin :19 which projects through the bottom of the drum in the same manner as do the leveling pins l0 and which terminates at its upper end in a laterally-extending arm or head 80 normally restures, disposed in annular fashion on their oppoing on the bottom of the recess 12 and extending sufilciently beyond and radially between adjoining intersecting arms of the spider 141 to be exposed therebetween for contact with a depending lug 8| projecting from the lever, 56. It will be noted in Figures 5 and 6, that this center pin arm is of less height or thickness than the heads of the leveling pins 10, so that in its normal position, with no coin in the coin slide, the top side of the arm is spaced from the bottom side of the spider M. The spring 69 applied to the lever 56 normally urges such lever to swing downwardly with its lug 8! in bearing or abutting contact with the center pin. When a coin or slug of a thickness approximating that Y of an acceptable coin reaches the stationof test, the center pin is shifted upwardly a distance approximating or less than the height of the headsof the leveling pins ll] so as not to disturb the spider 14, resulting in the lever 56 being swung upwardly against the resistance of its spring 69 in contact with the bottom side of the plate 59, whereupon the spring 54 associated with the locking-pin lever 54 acts to force such lever downwardly to retract the locking pin 53 from clutching engagement with the toothed disk 4i.

Should the coin inserted in' the coin slide be of less thickness than that of an acceptable coin, then there is not sufficient movement transmitted to the center pin 19 to disturb the lever 56 a sufficient amount to effect the retraction of the locking pin from the toothed disk, whereupon the scanning drum 2? is held against turning and the thin coin or slug attempted to be passed through the machine is rejected.

It will be understood from the foregoing that the scanning operations performed by the pins l0 or the center pin 19 may be independent or joint, depending on the characteristics of the particular coin inserted in the coin slide.

Certain types of slugs in circulation have embossments, such as lettering or ornamental figsite faces and adjacent the peripheries thereof, andwhi'le they may or may not pass the surfacecontour scanning test performed .by the leveling pins iii and the thickness test performed by the center pin E9, in conjunction with the leverage mechanism M, 55 and 56, I provide a frictional scanning or testing means operative on such slugs to positively reject them and prevent the coin-slide advancing its full stroke. This frictional scanning means is designed to frictionally grip or clutch the slug or spurious coin of this type in such a way as to hold the scanning drum 2? against turning; as does the locking pin 53, and thus prevent a coin-discharge stroke being transmitted to the coin slide 28. In the ;preferred construction of this scanning means shown in the drawings, it consists of a plurality of yieldable friction pins or elements 82 guided for vertical displacement in openings 83 formed in the bottom or hub portion of the drum and interposed radially between the leveling pins 10 but on a greater circumference where they are in a. position for operating upon the marginal or rim portion of the coin-surface. At their lower coin-engaging ends these friction pins have knifelike edges 84 disposed radially relatively to the drum-axis or coin for gripping or clutching engagement between embossments on such coin. Yieldable hangers 85 substantially in the form of leaf springs serve to support the friction pins 82 from the drum and hold them against turning and tend constantly'to force such pins downwardly into firm gripping contact with a coin.

During the scanning test of a coin, that is, after its insertion in the coin-slide 20 and its advancement to the testing station axially below the scanning drum 27, the coin is forced upwardly by spring pressure against the scanning elements l9, l9 and 82 by means of a platform preferably in the form of a channeled plate 86 arranged in the cross-shaped opening ll of the guide body l5 and supported or fulcrumed at its rear end on a ledge 8'1 formed in such body, While its opposite end is free to permit a vertical displacement of the plate. The flanges 88 of this channel plate engage corresponding longitudinal grooves 89 in the coin slide 28 and the bottoms of these grooves constitute abutments and limit the upward displacement of the plate. Extending from its opposite sides the channel plate has bearing shoes or lugs 96 which register with the lateral portions N3 of the body-opening I! and in the retracted position of the coin slide bear against its bottom side outwardly of the grooves 89, as shown in Figure 3. Leading rearwardly from the opposite marginal portions of the coinslide aperture 2! and in the vertical plane of the plate-shoes 90 are longitudinal recesses 9| into which said shoes are adapted to drop when the coin-slide is advanced to the testing or scanning station and continue in engagement therewith for the balance of the slide stroke. The

channel plate is constantly urged upwardly by a 1 bowed spring 92 held in place by a cover plate 93 applied to the underside of the guide member it. When the aperture of the coin slide reaches a position just short of being in axial alinement with the scanning drum 21, the plate-shoes 90 are forced into the marginal portions of such opening by the spring 92, the coin engaging and. straddling the flanges 88 of they plate 86 and being forced by the latter firmly against'the scanning pins ll], 19 and 82 and the serrated recess 23* of the secondary slide-opening 23. By preference, the bottom face of the'drum-hub 32 through which the several scanning pins project is concave or'archedin contour, extending inwardly from the serrated recess, as shown in Figures 5 and 6.

When the coin slide 20 has been advanced its full stroke to discharge an accepted coin, it is desirable to effect the return of the secondary slide or carrier 22 simultaneously with that of the coin slide, and to this end the rear' stop element 25 is attached to the free end of a laterally-movable spring arm B l which may be fixed at its opposite end to the companion stop element 25. The stop element 25 has a lateral extension 95 'which abuts the opposing edge of the guide frame l5 during the major portion of the slide movement and at its front end the carrier-slot 24 has an offset notch 96 into which the opposing edge 91 of said stop element is adapted to snap, by the pressure of its spring arm 94, when such element rides off the end of the chamfered edge 98 of the guide frame at the final portion of the slide-stroke. The moment the stop element 25 encounters the notch 96, the carrier 22 is coupled with the coin slide, so that when the latter is retracted the carrier moves simultaneously therewith until the scanning means 26 reaches its initial position, at which time the extension 95 of the stop element encounters the chamfered edge 98 of the guide frame, withdrawing such stop element from cou- 'pling engagement with the notch 96. and per- '7 another coin.

Briefly stated; the operation of the deviceis as follows: r

A coin is placed in the coin slide in the usual fashion and the slide advanced rearwardly to the coin-testing station. If the coin is an acceptable one, the tests thereon will not in any Way affect theprojection of the'locking pin 53, so that the toothed disk ill will, during a further advance of the coin slide,permit the free turning of the drum with'its gear at rolling over the 'teeth l l of the tappet bar 43 until such time as the coin registers with the opening it when the coin will drop by gravity therethrough. Should the coin be an unacceptable one and the tests thereon at the testing station cause an elevational displacement of the locking pin 53 into clutching engagement with toothed disk ll, in the manner heretofore described, then the scanning drum 2 will be clutched against turning, thereby preventing a full operative stroke .being transmitted to the coin slide and causing the normally-released trip dog 59 to be forced by the tappet bar i l into latching engagement with one or another of the teeth Si in thecoin slide. When thus latched against movement, the user of the slide must retract the coin slide to its initial, position because the slide will not function properly unless an acceptable coin is inserted in the slide.
